I'm currently working on an open-source project called checkd, which is a Cloudflare service worker designed to handle device authentication and state management using Apple's DeviceCheck API. The project includes an example iOS app and a worker implementation to demonstrate how the service can be integrated into a mobile app environment.

This project has been an exciting way to explore better securing my iOS apps. I'm looking forward to refining it further and would love to hear any feedback or suggestions from the community!
